Required device setting to perform a power frequency magnetic field test
To perform a 50/60 Hz magnetic field test, the NSG generator must be configured with the used hardware in the
menu:
Menu / SETUP / Equipment
1.
Variable transformer
:
- VAR 3005A-S16
2.
Magnetic current transformer
- MFT 30 (3 A range)
H-field
1 to 10 A/m
- MFT 30 (30 A range)
H-field
1 to 44 A/m
- MFT 100 H-field 80 to 1.000 A/m
The MFT 30 has two ranges and therefore the NSG generator list this current transformer
in the configuration for (3 A) and (30 A) range. Set the range switch of the MFT 30 to the
correct position before starting the test.
To adjust the Transformer factor, use menu / SETUP / TRANSFORMERS
The transformer factor is defined as follow:
Antenna current [A]
Transformer factor =
U prim MFT 30 [V]
For more information see chapter 1.4.2 current

Menu / SETUP / EXTERNAL COUPLERS
3.
Magnetic field antenna
:
- MFC 1000.1
The coil or antenna factor is defined as follow:
H-field antenna [A / m]
Coil factor =
I antenna [A]
